Reaction Steps

7-methoxy-thiochroman-4-one (700 mg, 4.27 mmol) was stirred with (4-methoxy-phenyl)-hydrazine (818 mg, 4.70 mmol, 1.1 eq.) in EtOH (40 mL, 0.1 M) and refluxed for 2 hours. EtOH was then removed from the mixture and EtOAc and saturated NaHCO3 aqueous solution were added. The organic layer was separated, dried over K2CO3 and concentrated. The residue was purified with flash column chromatography (4:1 Hexane:EtOAc) to yield the title product as a brown solid.
